{"id":"GHSA-m36x-mgfh-8g78","summary":"Subdomain Takeover in Interactsh server","details":"A domain configured with interactsh server was vulnerable to subdomain takeover for specfic subdomain, i.e `app`, Interactsh server before `\u003c 1.0.0` used to create cname entries for `app` pointing to `projectdiscovery.github.io` as default which intended to used for hosting interactsh [web client](https://github.com/projectdiscovery/interactsh-web) using GitHub pages. It turns out to be a security issue with a self-hosted interactsh server in which the user may not have configured a web client but still have a cname entry pointing to GitHub pages, making them vulnerable to subdomain takeover.\n\nThis issue was initially reported to us as a subdomain takeover for one of our domains that runs interactsh server by **Melih** at `security@projectdiscovery.io`, and after conducting an internal investigation, we determined that it was an issue with the default config of interactsh server affecting all the server running self-hosted instance of interactsh, as a result - cname entry has been removed in the latest release.\n\n#### Impact\nThis allows one to host / run arbitrary client side code (XSS) in a user's browser when browsing the vulnerable subdomain, for more details on the impact, please read this [detailed blogpost](https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more/) from Detectify.\n#### Patches\nUpdate to [Interactsh server v1.0.0 ](https://github.com/projectdiscovery/interactsh/releases/tag/v1.0.0)with `go install -v github.com/projectdiscovery/interactsh/cmd/interactsh-server@latest`\n\n#### References\nhttps://github.com/projectdiscovery/interactsh/issues/136\n\n#### For more information\nIf you have any questions or comments about this advisory:\n* Email us at [security@projectdiscovery.io](mailto:security@projectdiscovery.io)\n","aliases":["CVE-2023-36474","GO-2022-0372"],"modified":"2026-08-24T00:34:17.028984589Z","published":"2022-01-27T15:15:25Z","database_specific":{"nvd_published_at":"2023-06-28T22:15:09Z","cwe_ids":["CWE-79"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2022-01-24T22:24:55Z"},"references":[{"type":"WEB","url":"https://github.com/projectdiscovery/interactsh/security/advisories/GHSA-m36x-mgfh-8g78"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-36474"},{"type":"WEB","url":"https://github.com/projectdiscovery/interactsh/issues/136"},{"type":"WEB","url":"https://github.com/projectdiscovery/interactsh/pull/155"},{"type":"PACKAGE","url":"https://github.com/projectdiscovery/interactsh"},{"type":"WEB","url":"https://labs.detectify.com/2014/10/21/hostile-subdomain-takeover-using-herokugithubdesk-more"}],"affected":[{"package":{"name":"github.com/projectdiscovery/interactsh","ecosystem":"Go","purl":"pkg:golang/github.com/projectdiscovery/interactsh"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.0.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/01/GHSA-m36x-mgfh-8g78/GHSA-m36x-mgfh-8g78.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
